HYDROCABBON MINERS LAMP.

Specification of Letters Patent.

Application filed January 4, 1911.

Serial No. 600,690.

To all whom it may concern:

Be it known that I, JULns GoULn'r, a subject of the King of Belgium, and resident of Brussels, Belgium, have invented certain new and useful Improvements in Hydrocarbon Miners Lamps, of which the following is a specification.

This invention relates to a miners lamp.

In the drawings: Figure 1 is a vertical section of my improved lamp. Fig. 2 isa detail view illustrating one form of regulator. Fig. 3 is a similar view of another form of regulator. Fig. 4 is a vertical section of a modified form of lamp. Fig. 5 is a partial horizontal section on the line A, of Fig. 4. Fig. 6 is a vertical section of a further embodiment of the invention. Fig. 7 is a similar section of a still further form of the invention.

The miners lamp shown in Fig. 1 comprises a lamp body 1, in which is a mixing tube 2. The mixing tube is surrounded by an air inlet tube 3, which opens out above the body 1, where it is screwed into a tubular extension 4, on the said body. The tubes 2, and 8, are soldered to each other but have no other connection with the body 1, than the screw threads of the tubular extension 4. The tube 2, is provided at its upper end with a burner 5, having a gallery 7, to receive a lamp chimney 8. Over the burner 5, is an incandescent mantle 6. The upper wall of the body 1, is provided with a circular rib 9, which is threaded to receive the protecting cage 10, which supports a very thick second casing 11 and an antifire-lamp wire gauze screen 12. The casing 11 is constructed in a particular manner to permit of the passage of air, necessary for the proper burning of the lamp, while removing however any danger of explosion. To this end the said casing is cut away at its lower edge to form a number of openings 13, which are entirely covered by a ring 14 of wire gauze, secured on the outer surface of the casing.

The mixture regulating device comprises a small tube 15 fitting in and frictionally engaging the lower open end of the tube 2. The tube 15 is provided with openings 17 and 18 located at different levels and arranged in a special manner so as to correspond to openings 19 and 20 formed in the lower part of the tube 2 so that the interior of the tube 2, is in communication with the tube 3, and said tube 2, is also in communication with the interior of the body 1, thereby permitting air and combustible vapors to pass to the burner. It has been stated above that the openings are arranged in a special man ner; as a matter of fact, the openings 19 and 20 of the tube 2, are arranged so that when the tube 15 assumes such a position that its admission openings 17 for the combustible vapors are opposite the openings 19, the air admitting openings 20, are about half closed so as to admit to the, burner a very rich mixture. If the mixture is too rich the tube 15 may be adjusted to regulate the openings 19 and 20.

The regulating tube 15 may. be constructed in any suitable manner. Its construction may be such that it may be moved vertically as shown in Fig. 1, or byvrotating same as shown in Figs. 2 and 3.

As long as the volume of hydrocarbon vapor admitted is inversely proportionate to the amount of air introduced, the construction of the regulator is of little import-ance. The body of the lamp is filled with a porous mass, such as stone, felt, blotting paper made up into blocks, rolled sheets, washers and so on.

For the purpose of filling, the protecting cage lO. is unscrewed and the wire gauze 12, the casing 11, the chimney 8, and the burner 2, are successively removed so as to gain access to the open end of the tube 2. The

hydrocarbon (benzin) is then poured into the tube 2, after the opening 19 of the regulating device has been previously opened to its greatest extent. When the stone is well impregnated, which takes place nearly instantaneously, the lamp is turned upside down so as to cause the excess of fluid to escape, then the various parts named above are again placed in position.

When it is desired to light the lamp, a flame in introduced under the chimney 8, the air current set up in said chimney draws the air and the hydrocarbon through the tube 2, and as soon as the said mixture reaches the sleeve, it is ignited and burns normally. The lamp is closed again and the miner may use it at once. If, in spite of the adjusting effected when the lamp is lighted, the mixture will not be formed in the proportions required for a good lighting, it would be sufiicient to adjust the regulating device. v

The form of the invention in Figs. 4 and 5 differs from that previously described, in

that the upper edge of the lamp body is so constructed as to dispense with the air inlet 13, of the casing 11, as well as with the protecting wire gauze 14. This result is obtained by forming a groove 21, at the upper edge of the body 1, and coiiperating with said groove is a grooved ring 22 soldered, or otherwise secured to the body 1, the said plates having a groove 25, which with the groove 21, forms a chamber in which the dust particles and other impurities may settle. The chamber is formed with openings 24, for the passage of air necessary to promote combustion. On the top of the body 1, is a disk 26, provided with a central opening 27, to accommodate the tube 2. The disk 26, is provided with an annular flange 28, formed with exterior threads. On the disk is a washer 29, which fits snugly the tube 2, whereby to provide an air tight connection to insure the air passing through the openings in the chamber, and through the porous body. Arranged on the washer 29, is a packing ring 30, and a holding ring 31, for the casing 11, above which are two protecting wire gauze screens 32, and 33. Near the upper edge of the body 1, are hinged tongues 34, which are folded down over the edge of the disk 26, when the lamp is put'together.

In the construction shown in Fig. 6, the burner is located in the lower end portion of the lamp adjacent the base 36. The base is formed with a U-shaped duct 37 which communicates at one end with a burner provided with an extension 7 O, fitting in a washer 71, which is supported on rings 72 and 73, on the upper surface of the base 36. Interposed bet-ween the base 36 and the ring 72, is a Wire gauze 74 which prevents back firing. The tubular extension 70, is provided at its upper end with a grating 75, and is also provided with a gallery 76 for the chimney 77. The base 36, is provided on its upper surface with a threaded annular flange 39, which supports a thick chimney 40, the upper edge of which supports two protecting caps made of wire gauze. Screwed on the flange 39, is a ring of a gallery 41, the annular portion 42, holding in position the protecting caps, and a casing 40, in position. In the bottom 43 of the annular extension 42, are openings 44, and engaging the threaded flange 45 is a ring 46 of a sheet metal casing '47. The ring is also provided with an annular extension in which vertical openings 48 are formed. The ring 46, is provided with a vertical flange 49 in which notches 50 are formed for the admission of air. The flange 49 is extended as at 51, to form a support for the casing 47, the latter being covered at its top by a sheet metal plate. Below the cover plate the easing 47 is formed with openings for the escape of the burned gases. Located above the casing 47, is the receptacle to receive the hydrocarbon. Arranged inside a hollow body 52, is a double bottom 53, which communicates with the lower part of the casing 47 by means of a lower tubular extension 55, fitting in a tube 56. The latter is in turn engaged in a second tube 56 supported on the cover of the casing 47. The space 54, formed by the double bottom 53 also communicates with the inside of a regulator 57, by means of a central tubular extension 60. The regulator is substantially the same as that previously described, except the opening 58, of the outer tube is protected by a deflector 59 which is closed at the top, and is open at the bottom. The tubes 56 and 56 'are spaced from each other to form a passage through which the excess air drawn in at the lower part of the tube 56 may escape, said air passing through suitable openings formed in the upper part of the tube 56. The block which serves to retain the hydrocarbon is inclosed in a casing 61, and is held at a certain distance from the bottom of said casing by means of legs 62. The casing 61 has such depth that when it is placed in position, a space 63 is formed. A tube 64 communicates with the space 63, and its opposite end fits in a tube 65, the lower end of the latter fitting in the duct 37, of the base 36.

When it is desired to operate the lamp ust described, the block is held by the ears 66, and saturated with hydrocarbon by dipping it into a bath of this liquid, said block is then placed in its casing 61 and the carbureted air will at once be produced which owing to its specific gravity, will descend through the opening 67, and into the space 63, and thence through the tubes 64 and 65, and duct 37 to the burner, where it may be lighted. When the lamp is lighted, which it. is needless to say can only take place after the regulating device has been opened, all the parts of the lamp which have just been described are successively put in position again, whereafter they are secured by means of a stirrup 68, which is provided with looking means to prevent unauthorized persons tampering with the lamp.

The lamp just described operates substantially as follows: The heat evolved by the burner produces a current of air in the casing. The air entering through the openings 44, 50, 48, is heated a part of this air being drauin through the tube 56, to the space 54, and through the tube 60, to the regulating device. The air mixes with the vapors in the block, and thence is drawn into the space 63 and is directed to the burner.

The form of the invention shown by Fig. 7, differs from that shown in Fig. 6, in that the hydrocarbon reservoir instead of being positioned above the casing of the lamp is arranged below the burner. In this construction the Warm pure air enters the casing 47, and a pipe is connected thereto, the opposite end of said pipe communicating with an annular space 69, formed around the casing 61.
